The ship's engines and boilers were replaced by Parsons geared turbines and eight Admiralty three-drum boilers operating at 400 psi (2,758 kPa; 28 kgf/cm 2). [26] This saved some 2,800 long tons (2,800 t) of weight and allowed the two forward boiler rooms to be converted to 4.5-inch (110 mm) magazines and other uses.
[3] [5] [2] The atmosphere of Mars is much thinner and colder than Earth's having a max density 20g/m 3 (about 2% of Earth’s value) with a temperature generally below zero down to -60 Celsius. The average surface pressure is about 610 pascals (0.088 psi) which is 0.6% of the Earth's value.
The Type 38 at 128 cm (50.4 in) was the longest rifle of the war, due to the emphasis on bayonet training for the Japanese soldier of the era, whose average height was 160 centimeters (5 ft 3 in). [16] The rifle was even longer when the 40 cm (15.75 inches) Type 30 bayonet was fixed. The Type 38 was fairly heavy, at about 4.25 kg.
The gun had a muzzle velocity of 2,950 ft/s (900 m/s) [156] and an excellent range of some 1,800–1,500 yd (1,600–1,400 m). It was sensitive to sidewards movement; an attack required a dive from 5,000 ft (1,500 m) at a 30° angle with the turn and bank indicator on centre.
Helium has two abundant isotopes: helium-3, which is primordial with high abundance in earth's core and mantle, and helium-4, which originates from decay of radionuclides (232 Th, 235,238 U) abundant in the earth's crust. Isotopic ratios of helium are represented by R A value, a value relative to air measurement (3 He/ 4 He = 1.39*10 −6). [98]
